Product and version information:
The storage array was directly connected to the host through two redundant paths. A LUN was mapped to the host. The LUN was successfully partitioned and was allocated drive letters. An NTFS file system was created on the formatted LUN. The host performed read/write operations on the LUN and the LUN failed. In such a case, the following two situations may occur: VXVM could not update the LUN status in a timely manner. VXVM could not update the partitions created on the LUN in a timely manner. Symptoms are: Files could still be copied to the partitions created on the failed LUN, and these files were stored on the host cache. However, if the host powered off unexpectedly, the file data was lost.
If it is absolutely necessary to use SF for managing disks on Windows, users must be notified of the risks described in this case.
